Design Technology Paper 1

?
mechanical properties =
how a material reacts to an external force
1 of 12
compressive strength =
ability to withstand being crushed by pushing forces (compression)
2 of 12
tensile strength =
the ability to resist stretching or pulling forces (tension)
3 of 12
bending strength =
the ability to resist forces that may bend the material
4 of 12
shear strength =
the ability to resist sliding forces on a parallel plane
5 of 12
torsional strength =
the ability to withstand twisting forces from applied torsion
6 of 12
hardness =
the ability to resist abrasive wear e.g. scratching
7 of 12
toughness =
the ability to absorb impact force without fracture
8 of 12
plasticity =
the ability to be permanently deformed (shaped) and retain deformed shape
9 of 12
ductility =
the ability to be drawn out under tension without cracking, e.g. stretching a material into a wire
10 of 12
malleability =
the ability to withstand deformation by compression without cracking - increases with temperature rise
11 of 12
elasticity =
the ability to be deformed and then return to the original shape when the force is removed
